The thesis outlines the legal framework which Austrias animal shelters range in, especially focussing on the standards according to administrative law as well as depicting and analysing certain issues concerning other legal fields. Following the exposition of the fundamental principles of animal welfare according to constitutional law and the history of animal shelters, the legal bases of sanctuary work according to animal protection law as well as issues spanning other legal matter is dissected. Chapters 4 to 7 address the legal allegations in sanctuaries, especially defining legally uncertain duties. The duty to obtain a permit and the minimum requirements for animal shelters according to the law are discussed. Besides the both scientific and abstract examination, an interview conducted with Mrs MMag.a Dr.in Madeleine Petrovic, president of the Wiener Tierschutzverein and executive of the Wiener Tierschutzhaus Betriebsgesellschaft mbH, concerning the legal challenges in every day work at Austrias biggest animal shelter, is inserted in extracts where appropriate. Chapter 8 concludes by dealing with the sensitive matter of financing of sanctuaries and the realisation of public tasks by said animal shelters, especially touching on the current performance agreement between the province of Styria and the sanctuaries therein.
